Alternative
4(3*5+7)+3(2*5+5)=
4(22)+3(15)=
(4*22)+(3*15)=
88+45=133

For this case we have the following expression:

[tex]4 (3a + 7) +3 (2a + 5)[/tex]

We must evaluate the expression for the following value:

[tex]a = 5[/tex]

We have then:

[tex]4 (3 (5) +7) +3 (2 (5) +5)[/tex]

Then, rewriting the expression we have:

[tex]4 (15 + 7) +3 (10 + 5)\\4 (22) +3 (15)\\88 + 45\\133[/tex]

Answer:

The expression for a = 5 is given by:

[tex]4 (3a + 7) +3 (2a + 5) = 133[/tex]
